look for these before buying your smartphone

OPERATING SYSTEM

Android OS – by GOOGLE.

Windows OS – developed by MICROSOFT.

IOS – OS by APPLE

Blackberry OS – OS developed by RIM (RESEARCH IN MOTION)

Symbian – OS by NOKIA.

Out of these the most popular operating system as we all know is ‘ANDROID’. APPLE is still the top in technology but according to features provided by android with less price in India it is better than others. Symbian is almost out of race these days.

If you want to buy a mobile with android OS then go for its latest version Android - 4.4 Kit Kat. You won’t get bored of using ANDROID mobile.

 

SCREEN size and DISPLAY


The time has begun when the screen size of a mobile really does matter. We all neither want a small screen size mobile nor the biggest one. Large screen size mobile will not be comfortable to carry.

The best screen size of a mobile that you must go for is 4.5 to 5 inch. This is the perfect screen size of a smartphone.

And if you want a good quality display of your mobile then you must check the pixel per inch and resolution of the mobile, they should be more.

The acceptable pixel per inch (ppi) in budget smartphones is 218ppi, 233ppi, 256ppi, etc. go for these or more ppi according to your budget.

 

STORAGE

The internal storage\space of the smartphone should be more. Most of the apps are installed in the phone memory instead of the external SD card, if internal storage is less you can’t store much of your data, therefore internal storage should be more.

The internal storage most of the companies providing with their android mobiles is 4GB but the free space left for the user is between 2 to 2.5 GB the rest is used by the OS and its apps.

Choosing a mobile with 8GB internal storage would be better.

 

RAM

RAM (RANDOM ACCESS MEMORY) is used to store data temporarily. All the application while running their data is stored in the RAM.

More the RAM of a mobile more the multitasking you can do. Less RAM available in mobile can also stop any application to run.

The RAM of the mobile these days should be at least 1GB.

 

PROCESSOR

The processor is responsible for the smooth operation of any process in smartphones. However, you may not get the smooth operation if the processor is not good enough to handle the different operations in smartphones.

There are processors with different core (A processor core is a processing unit which reads in instructions to perform specific actions.), like single core, dual core, quad core, octa core.

More the core more the smooth operation, but the price of mobile will also increase with increase in cores.

You can go for a mobile with dual core or quad core, they can come under budget.

Dual core is good enough.

 

CAMERA

In a smartphone camera you can look for these:

Mega pixel – the 5 MP camera of a mobile is good enough.

Flash – there must be a LED flash to capture a good quality photo at night.

Auto focus– your smartphone must have an autofocus feature.

automobiles safety features - EBD,ABS and ESP

ELECTRONIC BRAKE DISTRIBUTION

Electronic brake distribution is a technology made as a safety function in automobiles that improves a vehicle’s braking performance and works in combination with an antilock brake system or ABS. EBD enables the braking force of a vehicle to be increased or applied automatically, depending on road conditions, speed of the vehicle, weight of vehicle.

 

In a car with no EBD or simple braking system, when the brake pedal is applied the brake fluid travels from the master cylinder to the brake cylinders. When the fluid goes inside the brake cylinder, the pressure of the fluid being applied forces the two pistons to push out resulting in the brake shoes or pads being pushed out. This push or pressure is in direct proportion to the push by the pistons, which causes the shoes or pads to rub against the drum or caliper. This reaction creates friction and decreases the turning of the wheels.

working of internal combustion engine (IC engine)

 

Want to know how bikes , cars and heavy trucks run and how they run even with big load , this is done by their main power supplier which is the 'engine'. The vehicles use internal combustion engine. The internal combustion engine is the power source for all modern vehicles. Its basic operating principle is that combustion, or the controlled, steady burning of air and fuel in the combustion chamber, creates power that forces components within the engine to move with great speed and force. The motion and force is transferred to the wheels of the vehicle through components of other automotive systems.

An understanding of the internal combustion engine, or ICE, requires an overview of the engine's major components. The components in direct contact with combustion are the cylinders, pistons, valves and spark plugs. Air from the vehicle's intake system and fuel from the fuel system is delivered to an area at the top of each cylinder known as the combustion chamber.
